' there are toothed wheels of equaldiameters,

its end a ratchetwheel e, which is exchangeable and may have any. selected number of teeth. In the course-of the rotation of the wheel a as indicated in Fig. l byflthe arrow h the wheel 2 is carried round, and strikes an abutment f,;whic h is verticallyadjustable and canalso be horizontally adjusted in a slotted support 9 on the foot of the machine, or some other convenient place, the abutment being fixed to this support by means of a set screw j. 1 When the wheel e strikes the upper straight'edge of this abutment it is rotated, as indicated, by the ar rowk in Fig. 2, and the worm a slightly rotates the worm wheel 6 as indicated by the arrow Z,.1n"the contrary direction to the arrow .72.

The extent of this backward rotation depends on the extent to which the edge of the abutment f engages the ratchet wheel e, and this'canbemegulated by adjusting the abutment on its support 9. v

This device disposes ofthe necessity of having-printing rollers of uniform circum- 'ference.

To allow of using box wheels having fewer than 27 teeth together with wheels having and 4 comprises a frame i, which can be vertically adjusted by means of a screw m, and made fast by bolts n. This frame can also be shifted forwards and backwards on I a support 0 by means of racks 7/ formed on said support, the frame carrying a spindle having toothed wheels (not seen in the draw ings) engaging said racks, a hand wheel '7) being securedto the spindle for manuallyrotating the same. The upper part '1' of the frame 2' is arcuate and serrated at its inner circumference, to receive the serrated bear ing-member s, which is of corresponding shape and thickness, serrated to engage the part 7*. This member s rests on the frame, locked by the teeth; The member s has bearings for three spindles, on two of which the thirdflspindle having a toothed wheel of smaller circumference, which drives the printing roller. Of thetwo uniform wheels, one designated a, is the automatic box wheel,

engaged with a driving wheel '0, and the other, designated it drives the box wheel t.

For "adjusting the bearing according to length of the spindles-the part .9 can be shifted by means of worm gear 2.

- The part 8 can be lifted out of the part 4' rotated, and re-engaged, and by adjusting the frames vertically and horizontally the wheel a can be engaged witha driving wheel 'v of any desired diameter.

It will accordingly be seen that with the four rollers there can be produced without change of position Four simple, original patterns,

.Six different two-color patterns;

Four different three-colored patterns; One four-color pattern, i that is to say fifteen patterns, whereas heretofore the utility of four rollers was limited to making four simple patterns, because the designs were not based on a system enabling them to be combined. Additional combinations can, of course, be made'by shifting the rollers, as is shown, for example, in Figs. 20 to 22. v

An important advantage of the invention is that it reduces the necessity of re engraving the printing rollers, because the uniform scale on which the patterns are designed enables. fresh patterns to be producedby permutation.1,;:lhis results in a great saving of 'material and labor, enabling production to be increased on a scale which can as yet.

hardly be estimated.

," The method can be applied to piece-goods as well as to wall paper and the like. Having now particularly described and ascertained the nature of my said invention and in what mannerthe same is to be performed, I declare that what I claim is 1. The process of printing atterns on fabrics, which consists in subjecting the fabrics to the action of a series of printing rollers each bearing a singlepattern, thereby to transfer to the fabrics thefcircumferential and longitudinal repeat of the single pattern of each of the series as a multi le of a common unit of measure, the lengt of said repeats being equal to the length of the least pf the circumferential and longitudinal repeat of the single pattern.

2. The process of printing patterns on fabrics, which consists in subjecting the fabrics to the action of a series of printing rollers of slightly different diameters each bear ing 'a' single pattern, thereby to transfer to the fabrics the circumferential and lon 'tudinal repeat of the single pattern of eac of the series as a multiple of a common unit of measure, and retardingthe rotation of some of the rollers in relation to the other rollers thereby to compensate for the difference in size of the rollers.

, 3. In a multi-color. printing apparatus, the combination of a rotatable sha carrying a printing roller, a sleeve secured to said shaft for rotation therewith, a driven member mounted on said sleeve for rotation relative- 1y thereto and adapted to receive motion from a suitable source of power, and means for locking said member and sleeve for rotation together and adapted to cause a lag in the rotation of the sleeve once during each complete revolution of said driven member.

4:. In a multi-color printing apparatus, the combination of a rotatable shaft carrying a printing roller, a sleeve secured to said shaft for rotation therewith, a gear Wheel mounted on said sleeve for rotation relatively thereto, means carried by said sleeve and wheel for locking them for rotation together, and means operative once during each complete rotation of said wheel to engage said locking means and cause a lag in the rotation of the sleeve.

5. In a multi-color printing apparatus, the combination of a rotatable shaft carrying a printing roller, a sleeve secured to said shaft for rotation therewith: a driven member mounted on said sleeve for rotation relatrve- 1y thereto and adapted to receive motion from a suitable source of power, a worm wheel carried by said sleeve, a shaft mounted for rotation in bearings carried by said driven member, a worm carried by said shaft in engagement with said worm wheel, and means for causing a partial rotatlon of the worm thereby to cause a lag in the rotation of the sleeve once during each complete rotation of the driven member- 6. In a multi-color printing apparatus, the combination of a rotatable shaft carrying a. printing roller, a sleeve secured to said shaft for rotation therewith. a driven member mounted on said sleeve for rotation relatively thereto, a worm wheel carried bv said sleeve, a shaft mounted for rotation inhearings carried by said driven member, a worm carried by said shaft in engagement with said worm wheel, and adjustable means for causing a partial rotation of the worm there: by to cause a lag in the rotation of the sleeve once during each complete rotation of the driven member.

7. In a multi-color printing apparatus, the

combination of a rotatable shaft carrying a printing roller, a sleeve secured to said shaft said worm shaft for rotation therewith, and

a stop member adapted to engage said ratchet wheel once during each complete rotation of said driven member thereby to cause a partial rotation of said worm and produce a lag in the rotation of the sleeve.

8. In a multi-color printing apparatus, the combination of a rotatable shaft carrying a printing roller, a sleeve secured to said shaft for rotation therewith, a driven member mounted on said sleeve for rotation relative- 7 1y thereto, a worm wheel carried by said sleeve, a shaft mounted for rotation in bearings carried by said driven member, a worm carried by said shaft in engagement with said worm wheel, a ratchet wheel removably 7 carried by said worm shaft for rotation therewith, and an adjustable stop member adapted to engage said ratchet wheel once during each complete rotation of said driven member thereby to cause a partial rotation of said worm and produce a lag in the rotation of the sleeve, the organization being such that the extent of said lag may be varied.

In testimony whereof I have signed my name to this specification.
